发明名称 VTR having magnetic-head array capable of recording/reproducing signals of a plurality of recording systems
摘要 Disclosed is a VTR of the helical scan type having a plurality of rotary magnetic heads. This VTR can select one of a first and a second signal recording forms which are different from each other, and record signals on a magnetic tape. In the first recording form, a frequency-modulated video signal including a luminance signal and a color signal and a frequency-modulated sound signal are recorded on the same track so as to be superimposed one on the other. In the second signal recording form, a frequency-modulated luminance signal and a frequency-modulated color signal are recorded separately on tracks adjacent to each other. This VTR has compatibility with respect to the recording/reproducing of two different signals.
